Please include the imports required for all the classes.

Thanks

Maybe you should only create cropped bitmap the first time you will draw it and store in a Bitmap variable in your custom class, for example in your onDraw() method:

if (roundBitmap == null) {
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();

        roundBitmap = getCroppedBitmap(bitmap, w);
    }

    canvas.drawBitmap(roundBitmap, 0, 0, null);

Maybe with this approach we should also check if image source change and roundBitmap must be recalculated.

Thanks!
David.

How to use this with ListView?

Creating a cropped bitmap on every draw call is insufficient I think. This is a better implementation.

Thanks. But can you please add your name (and the names of those who might have "inspired" or "helped" you) in the comments section. I hate copy and paste without giving the author(s) proper credit. For now, I am using Permita and the GitHub URL.

@kumarkundan: you can use this in xml as a view .. just use the header tag as
<your.package.name.MLRoundedImageView

/> thats all..

int w = getWidth(), h = getHeight();
int radius = w > h ? h:w; // set the smallest edge as radius.
Bitmap roundBitmap = getCroppedBitmap(bitmap, radius);

@L-Briand

for those who wants a center crop
create a Rect like this

int rad = radius/2;
Rect rectSrc = new Rect(
    sbmp.getWidth()/2 - rad,
    sbmp.getHeight()/2 - rad,
    sbmp.getWidth()/2 + rad,
    sbmp.getHeight()/2 + rad
);

and draw the bitmap like this
canvas.drawBitmap(sbmp, rectSrc, rect, paint);

I added one more button, when the button was clicked, it open the gallery, let user select the picture and inflate into your CircleImageView. everything was OK.
but, somehow, Some pictures auto rotated in CircleImageView.
I'm a newbie in Android, so, Could you please help me, how do I disable the auto rotation?
Thanks.

Please change 27-28 lines to:

    Bitmap b;

    try {
        b = ((BitmapDrawable) drawable).getBitmap();
    } catch (ClassCastException e) {
        Log.e(TAG, String.format("You can't use %s!", drawable.getClass().getSimpleName()), e);
        return;
    }

    Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);`

for cases if somebody trying to use LayerDrawable, for example.
